Description

Technical Field

[0001] The invention belongs to the technical field of engineering mortar filling equipment, and particularly relates to an anchor bolt hole mortar filling device and method. Background Art

[0002] Typically, compressor foundations are pre-buried with anchor bolts. The compressor is installed on the foundation and subgrade. The foundation and subgrade absorb the compressor's unbalanced forces and torque, transferring them to the soil. They also maintain the proper alignment and assembly clearances for the compressor components. Without a sound foundation, the compressor components will not be properly aligned and assembled properly, leading to problems and impacting safe operation. There are many types of anchor bolts, which connect the compressor unit to the foundation. In practice, casing is buried during foundation construction, and anchor bolts with anchor plates are inserted during compressor installation.

[0003] After the anchor bolts are installed, secondary grouting is often required. The main purpose of using mortar is to ensure good fastening and to form a whole with the sealing mortar on the foundation, with high strength. At the same time, it increases the natural frequency of the equipment and prevents equipment vibration. However, the contact area between the anchor plate of the anchor bolt and the foundation is small and the gap is narrow, which makes the mortar grouting operation more difficult, causing certain difficulties in construction. Summary of the Invention

[0004] The purpose of the present invention is to provide a mortar filling device and method for anchor bolt holes to solve the problem in the prior art that the gap between the anchor bolt anchor plate and the foundation is narrow and inconvenient for mortar filling and reinforcement when such large equipment passes through pre-buried anchor bolts.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A mortar filling device for anchor bolt holes, comprising an air compressor, a sand storage hopper, and a high-pressure sand conveying pipe provided on a sand filling vehicle; further comprising a sand filter baffle connected to the high-pressure sand conveying pipe and mounted above the anchor bolt hole; the sand filter baffle being composed of two cover plates rotatably connected to open and close, the sand filter baffle including a sand conveying channel connected to the high-pressure sand conveying pipe, and an exhaust channel provided on the cover plate;

[0007] Among them, the exhaust channel includes an exhaust port opened on the cover plate, and the exhaust port is symmetrically distributed at both ends of the two cover plate abutting surfaces. A top plate is movably provided in the cover plate, and the top plate is driven upward by the gas in the exhaust port. A connecting plate is provided on the cover plate to cooperate with the inclined surface of the top plate. When the air pressure in the anchor bolt hole is greater, the connecting plate abuts against the anchor bolt more tightly.

[0008] A further improvement is that the sand transport channel includes a transversely arranged annular channel and a plurality of sand discharge channels evenly arranged below the annular channel, and the sand discharge channel is arranged between two adjacent exhaust ports.

[0009] A further improvement is that the cover plate is semicircular in shape and has a concave structure at the lower end.

[0010] A further improvement is that the exhaust channel also includes a longitudinally arranged limiting channel and a piston movably arranged in the limiting channel, the upper end of the piston is connected to a connecting rod and extends to the top of the limiting channel, and the connecting rod is rigidly connected to the top plate; a plurality of through holes are opened at the connection between the limiting channel and the exhaust port, and before the anchor bolt hole is filled with mortar, the piston is located below the through hole.

[0011] A further improvement is that at least three filters with different apertures are provided in the exhaust port.

[0012] A further improvement is that rubber sealing pads are provided on the abutting surfaces of the two cover plates.

[0013] A further improvement is that a material baffle plate and an anti-backflow air port are sequentially provided on the sand filling vehicle and located between the air compressor and the sand storage hopper.

[0014] The present invention also provides a method for grouting anchor bolt holes using any of the above-mentioned devices, comprising the following steps:

[0015] S1: Sleeve the two cover plates onto the anchor bolts and cover the anchor bolt holes, while making the connecting plate abut against the sides of the anchor bolts. Then, tighten the two cover plates together by using the locking buckles provided on the cover plates, so that the sand filter baffle is placed in the gap between the compressor unit and the foundation.

[0016] S2: connecting the high-pressure sand conveying pipe and the sand conveying channel by locking the second buckle;

[0017] S3: Place the medium-coarse mortar to be filled into the sand storage hopper, then adjust the output power of the air compressor so that the air pressure of the air compressor can drive the medium-coarse mortar. Finally, start the air compressor, and the compressed gas compresses the mortar and continuously enters the sand conveying channel and the anchor bolt hole from the high-pressure sand conveying pipe to complete the mortar filling.

[0018] The beneficial effects of the present invention are:

[0019] 1) Compared with the prior art method of directly pouring mortar into the anchor bolt hole by holding a sand conveying pipe, the present application uses two semicircular cover plates to be sleeved on the anchor bolt, and the two cover plates are locked together. Compressed air carries mortar into the high-pressure sand conveying pipe and the sand conveying channel at the same time, so that the air pressure in the anchor bolt hole gradually increases. At the same time, the increase in bottom air pressure will cause the air flow to rise into the sand filter baffle, driving the top plate upward, so that the connecting plate matched with the upper surface abuts against the anchor bolt, preventing the mortar from overflowing from the connection between the two cover plates;

[0020] 2) The exhaust port of the present invention facilitates the exhaust of gas and the filtration of mortar. The exhaust ports are symmetrically distributed at both ends of the abutting surface of the two cover plates, making the gas exhaust more uniform and preventing the uneven upward force of the cover plates from causing the sand filter baffle to tilt relative to the anchor bolts. This also makes the surface of the anchor bolt holes poured by the mortar pouring equipment of the present invention smoother.

[0021] 3) In the present invention, the gas carries the mortar through the sand filter baffle into the anchor bolt hole, so that while the mortar is continuously poured into the anchor bolt hole, the internal air pressure increases. At the same time, as the internal air pressure gradually increases, the high air pressure makes the mortar in the anchor bolt hole denser, making the seal between the foundation and the anchor bolt more solid; when the piston moves up to above the through hole, the internal gas is discharged from the exhaust port to accelerate the internal mortar pouring speed.

DETAILED DESCRIPTION

[0027] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Example 1

[0029] like Figure 1-4As shown, a mortar filling device for anchor bolt holes includes an air compressor 51, a sand storage hopper 54, and a high-pressure sand conveying pipe 55 provided on a sand filling vehicle 5; a sand filter baffle 56 connected to the high-pressure sand conveying pipe 55 and mounted above the anchor bolt hole 4; the sand filter baffle 56 is composed of two cover plates rotatably connected to open and close, and includes a sand conveying channel 561 connected to the high-pressure sand conveying pipe 55 and an exhaust channel 562 provided on the cover plate;

[0030] Among them, the exhaust channel 562 includes an exhaust port 563 opened on the cover plate, and the exhaust port 563 is symmetrically distributed at both ends of the abutting surfaces of the two cover plates. A top plate 5625 is movably provided in the cover plate, and the top plate 5625 is driven upward by the gas in the exhaust port 563. A connecting plate 5626 is provided on the cover plate to cooperate with the inclined surface of the top plate 5625. The greater the air pressure in the anchor bolt hole 4, the tighter the connecting plate 5626 abuts against the anchor bolt 3.

[0031] Compared with the prior art which directly pours mortar into the anchor bolt hole 4 by holding the sand conveying pipe, the present application uses two semicircular cover plates to be sleeved on the anchor bolt 3, and locks the two cover plates by tightening the buckle 564, and then drives the air compressor 51, and the compressed air carries the sand into the high-pressure sand conveying pipe 55 and enters the sand conveying channel 561 at the same time. The covering area of ​​the sand filter baffle 56 in the present application is smaller than the area of ​​the anchor bolt hole 4, so that the air pressure in the anchor bolt hole 4 gradually increases. At the same time, the increase in the bottom air pressure will cause the airflow to rise into the sand filter baffle 56, driving the top plate 5625 upward, so that the connecting plate 5626 with the inclined surface contacts the anchor bolt 3, preventing the mortar from overflowing from the connection between the two cover plates.

[0032] The sand transport channel 561 includes a transversely arranged annular channel and sand discharge channels 5611 evenly arranged below the annular channel, and the sand discharge channel 5611 is arranged between two adjacent exhaust ports 563 .

[0033] The setting of the exhaust port 563 in the present invention facilitates the discharge of gas and the filtering of mortar, and the exhaust port 563 is symmetrically distributed at both ends of the abutting surfaces of the two cover plates, so that the gas discharge is more uniform, thereby preventing the uneven upward force of the cover plates from causing the sand filter baffle 56 to tilt relative to the anchor bolts; making the surface of the anchor bolt hole poured by the mortar pouring equipment in the present invention smoother.

[0034] In order to further facilitate the locking operation of the sand filter baffle 56 and occupy a smaller area, the cover plate is specifically semicircular and has a concave structure at the lower end.

[0035] In the present invention, the exhaust channel 562 also includes a longitudinally arranged limiting channel 5621 and a piston 5622 movably arranged in the limiting channel 5621. The upper end of the piston 5622 is connected to a connecting rod 5623 and extends above the limiting channel 5621. The connecting rod 5623 is rigidly connected to the top plate 5625; a plurality of through holes 5624 are opened at the connection between the limiting channel 5621 and the exhaust port 563. Before the anchor bolt hole 4 is filled with mortar, the piston 5622 is located below the through hole 5624.

[0036] Combine Figure 4 As shown, during the mortar pouring process, the gas carries the mortar through the sand filter baffle 56 into the anchor bolt hole 4, so that the mortar is continuously poured into the anchor bolt hole 4, and the internal air pressure increases, causing the piston 5622 on the sand filter baffle 56 to move upward, driving the connecting rod 5623 to move up and push up the linkage top plate 5625 to drive the connecting plate 5626 to abut against the outer wall of the anchor bolt 3 to prevent the mortar from overflowing from the contact surface of the two cover plates, thereby improving the flatness of the grouting surface. At the same time, due to the gradual increase in internal air pressure, the high air pressure makes the mortar denser in the anchor bolt hole 4, making the mortar seal between the foundation 2 and the anchor bolt 3 more solid; when the piston 5622 moves up to above the through hole 5624, the internal gas is discharged from the exhaust port 563 to accelerate the internal grouting speed.

[0037] It should be noted that in the present application, the piston 5622 can use a counterweight block with a certain mass, so that the counterweight block can be driven to move upward only when the internal air pressure reaches a certain value. That is, as the internal air pressure of the anchor bolt hole 4 gradually increases, it is convenient to increase the downward pressure on the injected mortar, thereby improving the firmness of the mortar and the anchor bolt.

[0038] In order to facilitate exhaust and filtering of mortar at the same time, at least three filter screens 5631 with different apertures are provided in the exhaust port 563 , and the mesh size of the filter screens 5631 is set according to the mesh size of the gravel in the mortar.

[0039] In the present invention, rubber sealing pads are provided on the abutting surfaces of the two cover plates, the side surfaces of which are in contact with the anchor bolts 3 and the bottoms are in contact with the surface of the foundation 2, playing a sealing role during the mortar pouring process.

[0040] In the present invention, a baffle plate 53 and an anti-backflow air port 52 are sequentially provided on the sand filling vehicle 5 and located between the air compressor 51 and the sand storage hopper 54. The baffle plate 53 is set to prevent sand from flowing back into the anti-backflow air port 52, and the anti-backflow air port 52 can prevent sand-carrying gas from flowing back into the air compressor 51.

[0041] The present invention provides a method for grouting anchor bolt holes using any of the above-mentioned devices, comprising the following steps:

[0042] S1: Slide the two cover plates onto the anchor bolts 3 and cover the anchor bolt holes 4. At the same time, make the connecting plate 5626 contact the side of the anchor bolt 3. Then, use the locking buckle 564 provided on the cover plates to condense the two cover plates so that the sand filter baffle 56 is placed in the gap between the compressor unit 1 and the foundation 2.

[0043] S2: The high-pressure sand conveying pipe 55 and the sand conveying channel 561 are condensed by the locking buckle 2 6 to make them communicate;

[0044] S3: The medium-coarse mortar to be filled is loaded into the sand storage hopper 54, and then the output power of the air compressor 51 is adjusted so that the air pressure of the air compressor 51 can drive the medium-coarse mortar. Finally, the air compressor 51 is started, and the compressed gas compresses the mortar and continuously enters the sand conveying channel 561 and the anchor bolt hole 4 from the high-pressure sand conveying pipe 55, thereby completing the mortar filling.

[0045] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
